of high-strength annealed ductile iron, these Steel Machine Rollers have
swivel tops that
rotate 360° on chrome steel ball bearings to allow for easier turning. The
rollers form a "tank track"
to revolve around a center load bearing plate in the frame to provide
The weight of the load is transferred directly from the load bearing plate
to the rollers, eliminating
axle friction and requiring less power to start and move. A spring loaded
locking mechanism on the
swivel tops, except on model VHMS-2, can be engaged in detents at 45°
intervals. These units are
virtually maintenance free. Steering bars split in two and connect with
sleeve for easy storage.
